LOOKOUI' OR DOOR-PEEP.

To all whom it may concern.'

Be it known that I, FRANZ LAIBAGH, a citizen of the United States,resident of New York, county of New York, and State of New York, haveinvented certain new and useful Improvements in Lookouts or Door-Peeps,of which the following is a specification.

This invention relates to improvements in lookouts or door peeps, suchas are used in connection with doors of`dwellings, lodges and the like,and has as its special object the provision of means whereby, beforeopening the door, a person desiring admission is subjected to a visualexamination from within; and a further object is to provide means,combined with the apparatus, whereby the physiognomy of the partydesiring admission may be subjected to light so as to assist inrecognition.

Another object is to provide means whereby the lighting device isoperated by ma.- nipulation of the Shutter covering the aperv turethrough which the view is taken and also means whereby the area of theaperture may be restricted or enlarged in the same eye piece.

These and other like objects are attained by the novel construction andcombination of parts hereinafter described and shown in the accompanyingdrawings, forming a material part of this speciication, and in which:-

Fig. 12 is a side elevationalview showing a further modification oflookout, in a simple form without lights.

Fig. 13 is a transverse sectional view taken on line 18-18 of Fig. 12,and

As illustrated, the eye piece 35, being of cup formation is iiXedlyattached to a h ollow casing 36, secured to the woodwork 1I, by means ofscrews 37 or like fastenings. A tube 38, engaged with the casing passesthrough the woodwork and has at its outer end a transparent plate 40preferably covered by a screen 41, both being held by the cap 42,attached by screws 43 on the outer side of the door.

In the slot 44, formed transversely through the base of the cup 35, isoperatively engaged two shutters, respectively 45 and 46, the latter,outmost shutter having a relatively narrow slot 47 extending in from itsupper edge, a similar slot 48, being formed in the lower edge of theshutter 45. Both shutters are pivoted on the screw 49 and operatedthrough the inner or lower shutter 45, having an extending flange 50 tobe clasped by the lingers of the operator. A flat spring 52, is securedto the lower side of the base of the eye piece 35, the free end normallyholding the front or smaller shutter 46 in a closed position. Alsoformed with the inner shutter 45 is a reversely formed flange 55,adapted to make contact with a similar flange 56 at the extending end ofthe outer shutter, so that when the shutter 45 is partially raised theopening 48 registers with the opening 47, thereby permitting a viewthrough the openings.

In operation when the shutter 45 is fully raised, the Harige 55 makescontact with the flange 56 raising the outer shutter so that the entireaperture through the tube 38 is displayed. The spring 52 at this timeengages with the ends of the shutters to hold them in an uprightposition.

Secured upon the inner side of the door 11, is a casing 65, and upon theoutside `a reflector 66 is held by the fastenings 67 the reiectorcontaining an electric lamp 68, engaged in the socket 69, secured on theouter side of the door. At the extreme outer end of the reflector 66, isa transparent plate 72,

lield in removable engagement. by a ring 70 formed with the lugs 71,engageable with the outturned edges of the reflector in such mannerthat. by raising the ring, the transparent. plate 72 may be removed inan obvious manner.l

In order to energize the lamp 68, by means of the battery carried in thecasing 65, one of the terminals 74 of the battery 7 5 is connected witha wire 76, to the pivot screw 49,-while the other Wire 77, from theopposite terminal 73, leads to a binding screw 78, another binding screw79, is connected with a wire 80, attached to the insulated screw 81,extending from the casing 36 in such manner as to clear the shutterswhen they are operated except in the event that light is desired,whereupon the shutter 4.5 when opened is firmly pressed back so as t0make contact with the insulated screw 81, thereby closing the circuitthrough the wires 82 and 83 leading to the electric light socket. Thusthe vlight may be used or not, and in no wa)T affects the operation ofthe lookout.

In Figs. 5 to 8 inclusive is indicated a further modification in whichthe several apertures, in place of being circular, are formedrectangular. In other respects the lighting means are substantiallythesame. The eye piece 85, however, has engaged at the outer end amagnifying lens 86, held in position by a cap 87, another lens 88 beingsecured in the tube 89, formed with the eye piece and which passesthrough the casing 90, and contains two shutters 92 and 9 3, the formerhaving a narrow central slot 94, and engaged at its upperv1 edge with aspindle 96, pivoted in the eye piece 85 and having an extendingoperating knob 97 so the shutter can be turned permltting a view to betaken through the slot 94, or if the spindle be further turned, the endof the shutter 92 makes contact with the shutter 93 hinged upon a pivot98. l The two lenses shown in Fig. 6, give a more extensive view thanplain lass and are specially applicable for use w1th thick doors orwalls and the tube flanges 91 holding the lenses are preferably made ofrubber, thereby renderin the construction dustproof.

One of e ectric wires as 76 is connected with an insulated screw 100,set in the casing-90, while the other wire 80 engages with a screw 101.A spring lever 102 fixed upon the eye piece is engageable by the knob 97when the latter is operated and which 1s pressed outward b the spring102. When the knob is presse in, the inner end of the spindle 96 makescontact with the screw 100, therebv forming a circuit and causing thelamp 68 to glow asin the case before meni tloned.

Figs. 9 and 10 show another slight modication in which a single shutter105 is secured to an actuatlng spindle 106, provided reame@ with a knob107, which when pressed inwardly causes thespring 108 to make contactwith the screw or nut 100.

In Fig. 11 a still further modification is shown, in which a singleshutter 110 has secured on its lower side a projection 111, having asingle central indentation 112, engageable with a spur 114, connected tothe wlre 76, thus when the shutter is open, contact is made between thespur and the indentation which serves to lock the shutter.

Figs. 12 and 13 show another modification in which a hinged shutter 116is operated in the manner before described and held normally out fromengagement with the contact screw 101, by means of a fiat spring 117 sothat the shutter may be raised and then pressed toward its supportwhereby contact will be made.

Fig. 14 indicates a rectangular lookout 120 in which is ivoted a shutter121, a spindle Y 122 passing t rough its center provided with I clann asnew and desire to secure by Letters Patent, is

1. In a lookout, the combinatlon w1th an eye piece, of two shuttersoperable therein,

one of said shutters having a narrow aperture, the other of saidshutters having an aperture registerable therewith upon movement of theyrst named shutter and means whereby the full opening through said eyepiece may be disclosed.

2. In a lookout, the combination with an eyepiece, a casing to whichsaid eyepiece is attached, a tube engaged with said casing, atransparent plate at the outer end of said tube, a screen covering saidplate, and a cap holding said screen and plate in their relativepositions, operably arranged in sald eyepiece, means for operating saidshutters, means carried by one of the shutters for actuating the other,a retiector opposite to said eyepiece, a lighting means within thereiector, and means operated by one of said shutters for causing saidlighting means to glow, substantially as described.

3. In a lookout, the combination with an eye piece secured upon one sideof the support, a reflector secured upon the op osite side of saidsupport and a source ofp electrical energy, of a lamp carried in saidreflector, said lamp being connected with said source of electricalenergy, one or more shutters in said eye piece, means for operating saidshutters, means for forming a circuit whereby said light is caused toglow when said shutters are opened and means for holding said shutterswhen in an open position.

4. In a lookout, the combination with an eye-piece secured upon one sideof a support, a reliector secured upon the op osite side of said supportand a source of e cetrical energy, of an electric lamp carried in saidreflector, said lamp being connected with said source ofelectricalenergy, one or more shutters in said eye-piece, means foroperating said shutters, and means for forming a circuit wherebysaidelectric lamp is caused to glow when said shutters are in an openposition.

In testimony whereof I have alxed my signature.
